19 Claims.

This application is a division -from the original specification of Lucian C. Jackson, Internal combustion engines, Serial No. 871,042, filed Nov. 9, 1914 and patented Aug. 26, 1919, Patent No. 1,314,487.

This invention relates to internal combustion engines and' more particularly to the general engine structure.

It has for its'objects to provide an improved, durable and efficient engine; in an improved method of Water jacketing all operating parts; and in particular an improved method of enclosing and housing all moving parts and especially all electrical generating and. distributing apparat-us and connections as Well. as other adjuncts, thereby excluding all foreign matter from their working parte or which might in any way interfere with their proper operation.

Wit-h these objects in view, the invention consists in certain features of novelty in the construction, combination and arrangement of parts by which the said objects and certain other objects Which 'will hereinafter appear are attained, the invention being more particularly pointed out inthe claims.

Like parts are identified by the same reference characters in both views.

In the drawing accompanying and forming a part of this specification, Figure 1 is a side elevation, partly in section as follows: At A and A as on line A in Fig. 2; at B as on line B gf Fig. 2; at.

C! as on line .C of Fig. 2 and at E as on line E of Fig. 2. Fig. 21s a sectional elevation on line H--H of Fig. 1; showing the valve mechanism and en- -closed water pumpand magneto on one side and the carburetor and exhaust pipe on the other.

4In the figures, I is the engine crankcase and having supporting arms 2, 2 etc. for supporting shaft for driving magneto 39 and water pump 42,

meshes with and is driven by a spiral gear (not shown) on vertical shaft 41.r The valve shaft 35, which is in the nature of a small crank shaft, is driven by the spiral gear 52 mounted at its center and which is in turn driven .by a. spiral gear (not shown) on` the upper end of vertical shaft 41.

51 is a cover for the spiral gears which drive the lmagneto 39 and water pump 42, and one of (ci. ias-iss) which gears is shown at 56. 34 is a cover for the Valve shaft 35 and its connections. 43 is a cover for the distributor 44 which is mounted on the end of valve shaft 35 and also for connecting wires 45 to the spark plugs 36, 36 etc. 48 is a main cover for the pump 42, magneto 39 and wires 43 to the Wire carrier 33 and thence to the spark plugs 31, 31 etc. 59 is one of the hand nuts for fastening the cover 48 to the engine. B9 is a handie for lifting cover v48. f

This covering of magneto and Wiring is for the purpose of protecting them from all dust and dirt and also'moisture which is liable -to short circuit any electrical apparatus which is not properly protected. 'I'his is also illustrative of the use of the invention to the protecting of all other electrical or other apparatus, as generator, pump etc. which may be in use on the engine.

58 is the water inlet for pump 42 and 49 the outlet and 4I the water manifold to the cylinders. 25 is the cylinder water outlet manifold. I3 is the cylinder wall; I4 the Water jacket space which extends around the valve mechanism as well as to the bottom of the cylinders making them' completely water-jacketed; and I5 is the water jacket: Wall.

2| is the cylinders of a four cylinder engine cast en bloc, as a convenient means of construction, though the headcan be cast separate as in the usual construction, for cleaning the top of the pistons though they can be as easily removed from below and the necessity forremoving the headv to take out and clean valvesv does not exist in my construction. My valves are easily removed from the top. and carbon does not interfere with their operation as with the poppet valve.

'Ihe parts of all cylinders and their valve mechanism isY the same. In'No. 1 cylinder 22 is the compression space; 23 a valve pocket extending up from the compression space; I8 is the piston and Bilthe connecting rod; I1 is a carburetor taking part of its air supply from the crank case and through the bearings which helps to cool the bearings and heat the air intake. A screen (not shown) is in this air intake near its connection to the crank case. I9 is one of two branches from the carburetor I1 which carries a fuel charge to cylinders Nos. 1 and 2 by means of a passage 53 'between cylinders I and 2 and to the chambers 28, 28 surrounding the valve mechanism of the two cylinders. A similar branch I9 (not shown) from the carburetor to a passage 53 carries the fuel to the cylinders 3'and 4 in like manner. is an exhaust pipe connecting with each of the four cylinders. l

.2l is a sleeve valve having ports 26 forinlet and exhaust to register ywith valve pocket 23. 5l is a piston valve in the sleeve valve 24. 55 is a bushing on the crank end of sleeve valve 2l to control its fuel intake ports from the carburetor. 30 and 3| are connecting rods between the sleeve valve 24 and the valve shaft 35 and the piston valve 54 and the valve shaft 35 respectively. 29 is the sleeve pin for connecting rod 30, and 32 is the crank pin. of sleeve 24. 33 is crank pin of Piston 54.

1 is the engine oil pan. 5 is an oil pump for circulating the oil in any approved manner to all of the bearing surfaces as required and from which the oil is returned'to be strained and again circulated. 8 is the oil pump shaft inserted into the lower end of vertical'shaft l1 and driven by the latter. l is a float in housing 59 and on an oil gauge, which extends up into the housing I6 to show the oil level in the oil Well II. opening by which the gear B and the vertical shaft I1 are lubricated by splash from the crank case I. i

The pad 2li on front of cylinder isf or supporting a fan which can be driven by a belt which runs through the slot 5|.
